# Composal vs Review Board

By Composal. Sources reviewed: 2026-10-15.

Review Board organizes human review of proposed source changes. Composal runs browser checks against deployed behavior and stores recordings and reproduction steps, rather than managing diff discussions.

## Composal

Composal sends AI browser agents to use your running web app and check the outcomes you care about. Define journeys as plain-English Scenarios, map existing flows with Discovery, or explore for bugs with Deep Scan. Runs keep recordings and reproduction steps so your team or coding agent can investigate a Finding.

## Review Board

Self-hosted collaborative code review

Review Board is an open-source platform for submitting changes, discussing diffs, and tracking review status. It documents review requests, repositories, and workflow integrations.

## Where each fits

Choose Review Board when self-hosted review workflows and control over review infrastructure matter. Choose Composal for browser QA evidence and exploratory findings. Teams can connect both stages in a release process.

## Try this evaluation

Submit a small application change through Review Board and deploy its preview. Compare reviewer discussion with Composal checks for the affected journey; note whether either tool exposes missing acceptance criteria.

### Coverage

Which user outcomes must this release prove, and which specialist checks must stay in your existing stack?

### Setup

Who prepares accounts, test data, permissions and access to the deployment being tested?

### Evidence

Can the engineer reproduce a reported failure from the recording and steps, without asking the tester to investigate again?

### Ownership

Who updates the checks when the product changes, and can the team review what a passing result actually proves?
